Na so e be for this forum I guess there are some account wey the owners don die if the forum confirm say the say the person don die them go lock the account another person no fit access am.
I don't think there's any way to tell if the owner of such account is dead or not and that's simply because no one reveals their true identity here on Bitcointalk. The only person I think his true identity wasn't hidden here is the legendary Hal Finney, who was once a member of Bitcointalk. But since after his death his account is sometimes used by his wife to pass on important messages to bitcoin talkers or even on his social media accounts.
It's very easy to tell, if an account had switched user because everyone here, has a specific posting style and when your account begins to post in a different pattern and gets noticed, it can be said to have been sold, bought or hacked by another person.here on Bitcointalk, people watch your every move so you've got to be careful.
Back to op, na true talk you yarn my brother, the idea don first dey my head before now. But I no sure say person go fit do anything about that matter. Death no be watin person dey plan for, but we all know say one day we go die leave all our earthly properties for this life. Bitcointalk na one special property for many of us here as we don invest our time and knowledge take grow our account e no o good make e just waste like that when we piae. D only thing wey you fit do na to introduce some of your family to Bitcointalk so Dem go still try study and grow them account. Apart from that nothing dey wey person go fit do. Sha make we hear from other members them.
